and suspending the lower half from the division-board to be operatedbyseparate cords, as hereinafter fully set forth.

Mydrawing is a perspective view illustrating the construction andoperation of my invention.

a a represent a hollow cornice designed to be attached to the top ofthewindow, facing in any suitable way. 11'?) represent a pair of doublepulleys mounted in each end of the cornice in anysuitable way. 0 0represent a double set of cords running over the pulleys b, andterminatingin a'single cord, which is attached to and winds upon thereel d, which has a ratchet to hold it stationary when the cord is woundupon it, and the blind thereby drawn up. ff is a horizontaldivisionboard in the center of the blind. One set of the cords cterminates in this'board, and the other setpass'es through andterminates at the bottom of the blind, where they are attached to thelower slat. The series of blind-slats are connectedby means. of suitabletapes and wires, to form flexible connections. g is a pulley,

I mountedin the middle of the division-board f f, over which anoperating-tape passes. Nos. 1 and 2 are the ends of the central cord or.tape h, connected with the edges of the slats for the purpose ofoperating them. By pulling the ends, Nos. 1 and 2, the blind-slats canbe alternately opened and closed. The ends of the central tape it on theupper half of the blind pass over a pulley mounted in the cornice.

By means of the division f f and independent central tapes h and k theupper and lower portions of the blind can be operated independently ofeach otherclosed above and open below, or vice versa; and by means ofthe double set of cords 0 c the loweror under half of the blind can bedrawn up and folded compactly against the division-hoard ff, so as toleave the lower portion of the window entirely unobstructed, and also atthe same time leave the upper division or top half of the blind in anunobstructed position, so that its slats can be operated and opened andclosed as may be desired.

I am aware that cords and pulleys have been used to open and close,slats and raise and lower blinds, and thatcentral bars arecomadvantageous.

I claim as my invention-- In a. window-blind, the suspendeddivisionboard ff, independent slat-operating tapes h and k, and doubleset of elevating-cords 0 a, substantially as and for the purposes shownand described.
